To all whom t may concern.-

Be it known that I, ROBERT MUNN DIXON, of East Orange, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements inLamps, of which the following is a complete specification, reference being had to the accompanying drawings.

The object-of my invention is to produce certain improvements in Argand lamps specially, but not exclusively, adapted for the burning of compressed gas.

Heretofore in. lamps of the same 'general type the mechanism Vcontrolling the air-supply has been suspended from the central stem of the burner and made separable therefrom, as by means of a bayonet-joint or like connection. I held in place by the mechanism suspended from the stem of the burner; but it has been necessary also to employ a clamp for supporting the globe at the upper end. vBy my invention I securely fasten the globe at the lower end, dispensing with the eXtra clamp at the upper end and the separable mechanism carried upon the stem of the burner. I also provide means for gai-ning accessto the interior of the lamp by a part hinged to a ring secured to the stem and employ a catch for sustaining the hinged part in the closed position carried exclusively upon the swinging part of the lamp, thereby affording means for lifting the hinged part and fastening it in place through the manipulation of the catch.

In the accompanying drawings, Figure I isl a sectional View of my lamp with some of the parts shown in elevation. Fig. II is an elevation of the catch detached. Fig. III is an elevation of the hinged part.

. Referring to the figures on the drawings, l indicates a burner of well-known construction adapted to discharge gas or similar illuminant from aring of downwardly-opening tubes 2.

3 indicates the central stem of the lamp.

l indicates a spider, which carries a foraminous cylinder 5, which constitutes the vertical portion of the flame-spreader. The spideris screwed, as indicated at 6, to the stem 3, which securely supports it in position.l The stem 3 extends down beyond the burner, and

. the ring 7 and the spreader, which are carried In the old-style lamps the globe is thereby, are situated below the burner. The spider carries a depending grooved ring 7, within the groove of which is supported the globe S of the lamp. A

Upon one side of the ring 7 are provided lugs 9, to which, as by a pintle l0, are secured the lugs l1 of a swinging frame I2. l The swinging frame is provided, with a groove 13, upon a packing-ring within which -is seated the flanged edge of a cup 14, which is secured in place, 'as bya ringl. The ring'15 is provided with projections 16, to which is secured, as by screws, the lower part of a foraminous spreader 17, which meetsthe spreader 5 atlS whenthe ring l2 is in the4 closed position.

Upon the side of the ring l2 opposite the hinge I provide a beveled face 19, to which is secured, as by screws, a spring-catch 20, that is provided with a finger-ring 21 for operating the catch and for lifting or dropping the cup 14.

In practice, as above described, the globe 8 Ais permanently carried upon the ring 7 of the spider 1l, which is screwed upon the end of the stem 3. The-vertical part 5 of the spreader is also carried in fixed relations to the burner by the spider. lVhenever the operator desires to gain access to the interior of the burner, he can do-so by operating the latch 20, whereupon the cup 14C, the ring I2, and the part 17 of the foraminous spreader drop away from the burner, giving easy access to the inyterior thereoffor lighting orclean'ing purposes. Y Y

By the employment of a spring-catch upon the hinged frame the latter may be raised or lowered without touching the cup and withlout danger of tarnishing its surface.

What I claim isl. In a lamp, the combination with a burner and its stem, of a spider and globe-supporting ring, the vertical portion of the spreader carried upon the spider, a hingedl frame sccured to the ring, and the lower portion of the foraminous spreader carried upon the frame, and adapted to form acontinuation of the first-named portion when., the frame is closed, substantially as set forth.

2. In a lamp, the combination with the burner and its stem extending centrally below the burner, of a spider supported by the IOO stem below the burner, a globe open at its lower end and supported upon the spider, a frame hinged to the spider, and a closing de- Vicegcarried by such frame for Closing the lower open end of the globe, substantially as set forth.

3. In a lamp, the combination With they burner and its stem extending centrally be- 10W Ialle burner, of a ring supported from Such stem and arranged below the burner, a globe open at its lower end and supported by said
